MX6SWT-A1-0000-000FA2 Equivalent & Substitute Parts

Part Overview

The MX6SWT-A1-0000-000FA2 is an XLamp® MX-6S neutral white LED (4750K) designed for surface mount applications requiring high luminous efficacy. This part operates at 20V forward voltage with a 60mA test current, delivering 126 lumens at 25°C. The component features a 120° viewing angle and is housed in a 2-SMD Gull Wing package measuring 5.00mm × 5.00mm.

The MX6SWT-A1-0000-000FA2 is classified as obsolete. Identifying equivalent substitute parts is necessary for design continuity, procurement flexibility, and long-term product support when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX6SWT-A1-0000-000FA2 is determined by the following critical parameters:

• Color and Correlated Color Temperature (CCT): White, Neutral 4750K
• Viewing Angle: 120°
• Package Type: 2-SMD, Gull Wing configuration
• Physical Dimensions: 5.00mm × 5.00mm footprint
• Thermal Resistance: 5°C/W
• Mounting Type: Surface Mount

The substitute part MX6AWT-A1-0000-000DA2 shares identical color specification, viewing angle, package footprint, and thermal characteristics. However, this substitute operates at significantly different electrical parameters: 3.3V forward voltage and 300mA test current, compared to the original part's 20V and 60mA. This electrical difference requires circuit-level design evaluation and is not a direct pin-compatible replacement without voltage regulation modifications.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-0000-000DA2 is the designated substitute for the obsolete MX6SWT-A1-0000-000FA2 based on matching color temperature, viewing angle, package footprint, and thermal characteristics. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The MX6AWT-A1-0000-000DA2 carries RoHS Compliance certification, whereas the original part's RoHS status is not specified. Both parts maintain identical Moisture Sensitivity Level (MSL 2A, 4 Weeks) and thermal resistance (5°C/W).

Critical design consideration: The substitute part operates at 3.3V forward voltage with 300mA test current, whereas the original operates at 20V and 60mA. This represents a fundamental electrical difference requiring circuit redesign. The substitute delivers 111 lumens at its test current compared to 126 lumens for the original, representing a 12% reduction in absolute flux output. The substitute achieves superior lumens-per-watt efficiency (112 lm/W versus 105 lm/W), indicating better energy conversion at its specified operating point.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000DA2 be used as a direct replacement without circuit modification?

A: No. The substitute part requires circuit-level redesign due to different forward voltage (3.3V vs. 20V) and test current (300mA vs. 60mA) specifications. Existing voltage regulation and current-limiting circuits must be re-evaluated and modified accordingly.

Q: What are the key compatibility factors between these parts?

A: Compatible factors include color temperature (4750K neutral white), viewing angle (120°), package footprint (5.00mm × 5.00mm), height (1.48mm maximum), and thermal resistance (5°C/W). These parameters ensure mechanical and thermal compatibility in the PCB layout and thermal management design.

Q: Why does the substitute part have an exposed pad in its package designation?

A: The MX6AWT-A1-0000-000DA2 features a 2-SMD Gull Wing Exposed Pad configuration, compared to the original's standard 2-SMD Gull Wing. The exposed pad provides enhanced thermal dissipation pathways to the PCB, improving heat transfer efficiency. This design change supports the higher current operation (300mA vs. 60mA) of the substitute part.

Q: Is the flux output difference significant?

A: The substitute delivers 111 lumens versus 126 lumens for the original, a 12% reduction in absolute flux. Application-specific photometric requirements must be evaluated. The substitute's superior lumens-per-watt efficiency (112 vs. 105 lm/W) may offset this difference in power-constrained applications.

Q: What is the product status implication?

A: The original MX6SWT-A1-0000-000FA2 is obsolete, meaning CreeLED, Inc. no longer manufactures or supports this part. The substitute MX6AWT-A1-0000-000DA2 is in active production, ensuring availability, technical support, and compliance with current industry standards.

Q: Are there moisture sensitivity considerations during assembly?

A: Both parts carry MSL 2A (4 Weeks) rating, requiring identical moisture control procedures during storage and assembly. No additional precautions are necessary beyond standard SMD handling protocols.
